Ethernet/IP tester offers one stop solution

A Next Generation Ethernet/IP Tester referred to as PacketExpert 10G that supports comprehensive testing of 10G and 1G Ethernet/IP networks has been unveiled by GL Communications. The PacketExpert 10G provides comprehensive testing of 10 Gbps/1 Gbps Ethernet/IP networks. It has two 10 Gbps Optical ports and two 10/100/1000 Mbps Electrical/Optical ports and capable of Bit Error Rate Testing (BERT), Smart Loopback, RFC 2544 Testing.                    

And now, PacketExpert 10G has been enhanced to support Wirespeed Record and Playback, Simulation of IP Links and Impairments (IPLinkSim), PacketBroker and Y.1564 Testing (ExpertSAM) test functionalities.

These tests are supported on each port independently for Wirespeed Ethernet/VLAN/MPLS/IP/UDP testing.  BERT is implemented for all layers. RFC 2544/Y.1564 is applicable for Layers 2, 2.5, and 3, and Loopback is applicable for Layers 2, 3, and 4.”He briefly explained the new functions: “Wirespeed Record application supports capturing traffic on both the 1G and 10G ports at full line rate simultaneously (10 Gbps * 2/1 Gbps *2), without disturbing the link. Internal 8GB of DDR3 memory allows capturing up to 8GB of traffic (from both ports) at full Wirespeed (10 Gbps/1 Gbps).

The captured traffic can be transferred to the host PC for offline analysis. Capture formats supported are PCAP, NGPCAP (popular wireshark formats), DAT (GL proprietary Raw format), HDL (GL proprietary PacketScan format).

Wirespeed Playback allows playback of canned traffic files (in PCAP/NGPCAP/DAT/HDL formats) over one/both ports at full 10Gbps rate, allowing real world conditions to be recreated in lab.

IPLinkSim emulates a bidirectional IP WAN link with varying capacities from 10 Mbps to 1 Gbps for the electrical interfaces, and up to 10Gbps on the optical interface.

This applicationcan be used to test performance of applications that uses Ethernet /IP based transport such as Web Services, Email, FTP, Database access, Enterprise Networks, Storage, Cloud Services, VoIP Services, Audio/Video Streaming and so on.

It offers an efficient and economical way to emulate terrestrial, wireless, Internet, satellite, or private network links.IPLinkSim can simulateall network impairment conditions of real world networks such as network latency, network delay variation (jitter), bandwidth, congestion, packet loss, packet FCS errors, packet bit errors and others. The link impairments can be applied independently to both directions.

The ExpertSAM application is used to validate Ethernet Service Level Agreements (SLAs) as per ITU-T Y.1564 standard.

It supports the two key Y.1564 subtests, the Service Configuration Test (SCT) and the Service Performance Test (SPT). SLA parameters measured include the Throughput, Frame Transfer Delay (FTD), Frame Delay Variations (FDV), and Frame Loss Ratio (FLR) service acceptance criteria to validate the network path under test.

Up to 16 streams can be tested with full Wirespeed (10 Gbps/1 Gbps).

The PacketBroker application allows PacketExpert to capture packets at Wirespeed (up to 10 Gbps/1 Gbps) non-intrusively over Ethernet (Electrical) and Optical ports at nano-second precision. PacketBroker supports both Tapping (Pass through mode), and Tap-Filter-Aggregate-Modification modes.

PacketExpert 10G includes report generation option to generate consolidated reports in CSV and PDF file formats. The reports include BERT Statistics, Tx/Rx Statistics, Tx/Rx Configuration details for each of the 10G ports.
